Question

a body starts from rest and covers a distance of 20m in 10sec find the velocity it occurs of the 10sec and the acceleration gaint​

Answer 1

If the body covers 20m distance in 10seconds, then as:

S=vt

or v = S/t

Putting values,

v = 20/10 = 2m/s

Thus the final velocity of the body is 2m/s.

Now, as;

Acceleration = vf - vi / 2,

a = (2 - 0) / 2

a= 2/2

a = 1m/s^2

Thus;

Velocity = 2m/s

Acceleration = 1m/s^2
